- Composting
Dead Poultry An acceptable system of disposal for dead birds
is essential to any well run poultry farm operation. Moreover, Virginia
law requires that poultry producers have an approved means for disposing
of dead birds. There are generally two categories of disposal problems:
(1) Normal mortality, which is typically about 0.1 percent per day,
but fluctuations up to 0.25 percent per day are not uncommon, and (2)
Whole flock disposal. Author: Eldridge R. Collins, Jr., Extension Agricultural
Engineer, VA Tech.
- Composting Layer Mortalities: An egg layer operation can successfully initiate composting as a means of managing dead birds by using the ingredient ratios with straw or hay as noted in Table 1. Once a supply of secondary compost is generated, this compost can be recycled as an ingredient to replace both manure and straw as noted by the recipe in Table 2. Water may need to be added because of the dry nature of recycled compost.
- Composting
Poultry Carcasses Current methods for the disposal of poultry
carcasses include hauling to a rendering plant, incineration, burial,
or composting. Rendering plants are rapidly decreasing in number and
of those that remain, many do not want to process poultry mortality.
Unless proper equipment is used, incineration may cause air pollution.
The fuel requirement for incineration is expensive also. Disposing of
carcasses in the ground can result in water pollution. Composting therefore,
appears to be the logical solution for many poultry operations. By:

- Composting
Poultry Mortalities Burying dead birds in disposal pits is a
common practice for poultry growers. Composting has been developed as
an alternative method of using dead birds in a more environmentally
sound manner. The composting process converts dead birds into a brown
humus-like material that can be spread on the land for crop utilization
and soil improvement. This relatively inexpensive method of composting
dead birds is gaining acceptance throughout the poultry industry. By:

- Storing
and Handling Broiler and Turkey Litter Application of livestock
and poultry manure on land has been a time-honored, convenient disposal
method that benefits the soil system. Overall, Virginia agriculture
uses more than a million tons of chemical fertilizer nitrogen (N) annually.
Manures can provide about 45% of this amount, or about 28% after allowing
for storage and handling losses. The amount of loss depends on the method
of handling and management involved. In recent years, large concentrations
of poultry on small parcels of land have made the manure disposal problem
more critical. When nutrients from manure, or commercial fertilizers,
exceed the ability of crops to utilize them, surface runoff and groundwater
pollution problems develop. This leaflet will outline management steps
to take advantage of the fertilizer value of your manure and litter
while minimizing potential damage to Virginia's water resources. Author:
